Answer:
Vasco da Gama's successful exploration of a sea route to India from Lisbon proved useful at developing a lucrative nautical trading relationship with India and all of East Asia.
Step-by-step explanation:
Vasco De Gama was the first European to find an ocean trading route to India. He accomplished what many explorers before him could not do. His discovery of this sea route helped the Portuguese establish a long-lasting colonial empire in Asia and Africa.
It was the basis for building a large trading empire. They established forts and trading posts on the coast and seized key ports around the Indian Ocean.
